Estate 18K Invisible Set Blue Sapphire Diamond Long Oval Cocktail Ring 5.80ctw

A superbly crafted cocktail ring executed in 18K yellow and white gold, showcasing approximately 4.50 carats of square-cut sapphires, invisibly set to form a seamless field of deep, royal blue brilliance. The sapphires are encircled by a delicate border of round brilliant-cut diamonds totaling approximately 1.30 carats, graded G to I in color and VS1–VS2 in clarity. The platinum-like white gold top enhances the vibrancy of the sapphires, while the yellow gold shank offers a warm, elegant contrast. Exceptional workmanship and design unite in this jewel, reflecting the level of precision and artistry seen in fine European creations of the late twentieth century.
